I can also say that.
NEL/CCL trains are fully automated. I guess we need to revive the newcomer's thread. We have new train enthusiasts who don't know what is AM,CM,RM
You peeked at the driver's console. Very funny, I doubt the CSO would see you sneaking up from behind. Anyway when the CSO drive in CM, they tend to be late for schedule by a few minutes.
By saying "peeked at the console", I meant over a period of over 5 stations. The driver was just standing there but he was not operating in any manual mode, I don't know why. I didn't sneak up on the CSO. I was standing right at the blockade but I could make out the speed markings on the speedometer. So its not so funny unlike what you'd probably imagine.

If you have the train 20m from CSP and it's still going at high speed, it would need to brake to 0km/h immediately (There are trains in other countries which can E-Brake 0km/h immediately). The force would be greater and if it's a locomotive. The trailers behind would "fly". The force has no where to go. So it is rebounded back to the other end instead. The force is also pushed downwards and against the force as a result of friction. Causing flat wheels too.
The reason for the slow approach can be explained by looking at this: http://www.youtube.com/watch?v=sNqKnfT52tw

As for acceleration, NEL trains slowly (relatively) increase power to full, while CCL depart at a lower power setting (CCL has no notches- it is linear), before going full throttle. This is why the acceleration feels different.
Ah alright thanks alot for all the crystal clarity =)
Anyway have you guys checked out the new B2 linkway from Raffles City to Esplanade station? Made me realise how close ESP is to CTH stn... If only there could be a linkway built to connect the 2 stations such that commuters can transfer without needing to travel up to DBG... If I'm not wrong, KL has a few stations that are in close proximity and are actually considered interchanges on the map (but I doubt they have seamless transfer)

I recall Bangkok had linkway under the length of the viaduct? It was years ago.

Yeah, I saw some on the KL rail map. Its quite expensive and tedious to have a line to crossover underneath each other tunnels

Lol. If you can't go higher! Go Under!
Lol Singapore is go lower lower and lower
Malaysia is go higher higher and higher. =P Like the hong kong 70m flyovers at where again?

We have high viaducts too! Jurong East... =P -
Not exactly. One of them is Bank Negara and PWTC where the KTM Komuter and STAR LRT intersects. A bridge links the 2 stations across the Klang River. Another is Dang Wangi and Bukit Nanas where the PUTRA LRT and KL Monorail intersects. Although they used to be unsheltered, shelters were built about a year ago to connect them. As KL does not have integrated ticketing, having seamless transfers would also prove to be useless.

I see...
Something similar : Canary Wharf London Underground station is closer to Heron Quays DLR station than the Canary Wharf DLR station it offcially interchanges with.

Maybe their upstairs come see. "Hm... This looks nearer, so we have interchanges with this." "Boss! But this nearer!" "What upstairs say, is never wrong! Don't argue"

No. This is because the route between the two Canary Wharfs are more wheelchair friendly.

Kelana Jaya Line got wad

The Kelana Jaya Line has tunels, but as the previous user has said, "...crossover underneath each other tunnels". The only line that runs undergrouns is the Kelana Jaya Line, or PUTRA LRT which means lines don't overlap underground.
-
Hi there, i dont know if this will work, but i think that underground lines should be replaced with SUSPENSION lines-that is something like a suspension bridge but instead there are suspended MRT stations and train tracks -
Do anyone have information on the crossovers on the NSL/EWL?
I need location (Between stations ___ and ___) and direction (EB to WB track)...

what is a crossover?

Originally posted by Larryteo:

Crossover train you mean?
They do NSL for a short while in the morning before crossing over to EWL via Jurong East at scheduled arrival timings. 7 trains in total per normal weekday.
-
Crossover, aka points, those zig-zag things that let you cross from the northbound track to the southbound track, .etc...

In order of CGL (CGA - TNM):
Changi Airport - Expo (Right after CGA): X-shaped crossover
Expo - Tanah Merah (Right after XPO): WB -> CAB (Changi Airport Bound)
Before EWL main line:
1: CAB > Depot track
2: Depot track -> WB
Merging with EWL main line:
1: MEB (Main Line East Bound, towards Pasir Ris) > CAB

~~~~~End of CGL sector ~~~~~~
Pasir Ris - Simei (Simei - Tanah Merah crossover sector can be found on above from Merging with EWL main line onwards)
Pasir Ris - Tampines (Right after Pasir Ris): Tandem crossover (WB > EB --- Oppose main traffic flow from either track followed by EB > WB)
Tampines - Simei (Right after Tampines): WB > EB (Oppose main traffic flow from either track)

Lavender - Bugis (Right before Bugis): EB > WB (Oppose main traffic flow from either track)
No crossover from Bugis - City Hall
City Hall - Raffles Place (Right before Raffles Place): SB > WB and EB > NB (Takes place on different level, no way to determine which comes first)
~~~~~ Marina Bay Appendix (So that I can do NSL until Orchard because there are no known crossover from Orchard to Raffles Place):
Raffles Place - Marina Bay (Right before Marina Bay terminus): Almost like a X-shaped crossover despite some claim it is NOT a X-shaped crossover like CCL Dhoby Ghaut. So unknown the shape but it is a crossover with NB > SB and SB > NB.
Marina Bay - Marina Pier: According to tender diagrams, it should be a X-shaped crossover or a SB > NB (Like Harbourfront style) if my memory did not fail me.
~~~~ End of Marina Bay appendix ~~~~~
There are no crossover from Raffles Place - Outram Park
Outram Park - Tiong Bharu: Middle track slidings in the following order >>>
1: WB > Middle track
2: Middle track > EB
3: Middle track > WB
4: EB > Middle track
With a dead end from both sides for the middle track sliding.
There are no crossover from Tiong Bharu - Redhill
Redhill - Queenstown (Right before Queenstown): EB > WB (Oppose main traffic flow from either track) ---- Possible to have Eunos - Queenstown shuttle train using "Marymount" style for the 2 "terminus", if you cant get the picture.
There are no crossovers from Queenstown to Clementi
Clementi - Jurong East:
Approaching UPD:
1: WB > EB
On outside UPD:
1: UPD > WB

Jurong East - Chinese Garden (Right after Jurong East only):
1: JEB > SB (MBB - Marina Bay Bound)
2: WB > MBB
P1: NB2 > SB2 (New Southbound, MBB) track *Premature track, only after JEMP then it can put as 3.
3: JEB2 (Jurong East Bound Morning Crossover track) > EB
P2: JEB2 > NB2 *Premature track, only after JEMP then it can put as 4.
~~~~ Choa Chu Kang Branch Line Appendix:
There are no crossovers after leaving Jurong East - Bukit Batok until approaching Bukit Gombak
Bukit Batok - Bukit Gombak (Right before Bukit Gombak):
JEB > MBB (Oppose main traffic flow from either track)
Bukit Gombak - Choa Chu Kang (Right before Choa Chu Kang):
Tandem crossover (MBB > JEB followed by JEB > MBB)
No crossover from Choa Chu Kang to Yew Tee
~~~~ End of Choa Chu Kang Branch Line Appendix ~~~~~~~~
No crossover after Jurong East to Lakeside
Lakeside - Boon Lay (Right after Lakeside):
Tandemn crossover (WB > EB followed by EB > WB --- Oppose main traffic flow from either track) --- Very near to X-shaped crossover
Right before Boon Lay:
Tandem crossover (WB > EB and EB > WB --- Oppose main traffic flow from either track)
No crossover from Boon Lay to Pioneer
Pioneer - Joo Koon (Right before Joo Koon):
Tandem crossover (EB > WB --- Oppose main traffic flow from either track and WB > EB)
No crossover after Joo Koon until Tuas Extension has built.
*Disclamier: For Tandem crossover on the (ex) terminus stations (Pasir Ris, Lakeside, Boon Lay, Joo Koon), I might get the direction wrong.
~~~~ End of EWL Main Line
NSL from Yew Tee to Orchard (For Jurong East - Yew Tee side please refer to Choa Chu Kang Branch Line Appendix and for Orchard - Marina Bay / Pier, please refer to Marina Bay Appendix earlier on EWL Main Line from Eunos - Joo Koon)
Yew Tee - Kranji (Right after Yew Tee):
MBB > JEB --- Oppose main traffic flow from either track
Approaching Kranji:
JEB > MBB --- Oppose main traffic flow from either track
No crossover from Kranji - Marsiling
Marsiling - Woodlands (Right before Woodlands):
1: SB (MBB) > Middle track
2: Middle track > WB (JEB)
3: WB > Middle track
4: Middle track > SB
With a dead end from both sides for the middle track sliding.
Woodlands - Admiralty (Right after Woodlands) *:
SB > NB (JEB)
Admiralty - Sembawang (Right after Admiralty) *:
SB > NB --- Oppose main traffic flow from either track
* Disclamier: This Northern side I am not so familiar as I do not frequent there. I maybe wrong for the direction as well
Sembawang - Yishun (Right after Sembawang):
NB > SB --- Oppose main traffic flow from either track (Quite like Eunos). The traffic light in SB platform is NW106
Approaching Yishun:
1: SB > Middle track
2: Middle track > NB
3: NB > Middle track
4: Middle track > SB
With a dead end on both sides of the middle track
Yishun - Khatib (Right after Yishun):
Tandem crossover (NB > SB followed by SB > NB --- Oppose main traffic flow from either track)
No crossover from Khatib - Yio Chu Kang
Yio Chu Kang - Ang Mo Kio (Right after Yio Chu Kang):
NB > SB
Approaching Ang Mo Kio:
1: SB > Middle track
2: Middle track > NB
3: NB > Middle track
4: Middle track > SB * (Disclaimer: I cant remember got such crossover or not)
Ang Mo Kio - Bishan (Right after Ang Mo Kio):
Middle track > NB
Approaching BSD:
SB > KDB (Kallang / Depot Bound especially if Kallang Line was built)
FKD (From Kallang / Depot especially if Kallang Line was built) > KDB *Quite like Jurong East's middle track, except the distance from it to the station.
Depot track > SB
Right before Bishan:
1: SB > Middle track
2: Middle track > NB
With a dead end on both ends of this short middle track. It is suspected this middle track is used daily for last Toa Payoh bound train to return to BSD without using Ang Mo Kio station at all. (NB > Middle track > SB - opposing main traffic flow, Depot track)
No crossover from Bishan - Braddell
Braddell - Toa Payoh (Right before Toa Payoh):
SB > NB, if my memory did not fail me. It must be only one side crossover and we can conclude that during the operation of first SMRT sector (YCK - TAP), 1 of the platform from each terminus was not used, just like present day Marymount / Harbourfront)
No crossover from Toa Payoh - Newton
Newton - Orchard (Right after Newton):
NB > SB - opposing main traffic flow (Quite like Bugis style)
~~~ End of NSL sector (Read on Marina Bay Appendix for Raffles Place and Marina Bay / Pier crossovers)
